Graph of Hyperbolic Sine Function

Plot Hyperbolic Sine and Exponential Functions

The hyperbolic sine satisfies the identity . In other words, is half the difference of the functions and . Verify this by plotting the functions.

Create a vector of values between -3 and 3 with a step of 0.25. Calculate and plot the values of sinh(x), exp(x), and exp(-x). As expected, the sinh curve is positive where exp(x) is large, and negative where exp(-x) is large.
